Since the introduction of the segway, DIYers have been building their own self-balancing transportation devices. Before you go off and build a full-size version, here's a simple project to help you learn the basics of control system design (the...

Magnetic levitation is awesome: From lightbulbs to trains and even hoverboards. This project, however, adds a whole nother level of awesome. Instead of using a static electromagnet, this electromagnet is attached to a CNC-like device with an X,...

We've seen open source computing power grow steadily over the years: First the Arduino, then the Raspberry Pi, and now the open source laptop. Yes, you read that correctly: the goal of this project is to create a laptop built entirely with...

Sure, 7-segment displays are common electronic components we see everyday. This, however, is an entirely mechanical version which morphs each minute as the time changes. To accomplish this, it uses lots of small servo motors to manipulate each...

We've covered some neat high speed photography projects in the past (some which use Arduino) and here's another awesome project to add to our collection. The device above triggers a camera when a certain magnitude of sound is captured. It...

Have you ever wondered where all those magical Arduinos come from? Surprise! They come from Torino, Italy. The video below will walk you through the PCB manufacuring and assembly process. A quick history lesson for you: this revolutionary...

Who doesn't love the Back to the Future series and who could forget Marty's hoverboard? Now you can build your own desktop version using electromagnets and a hoverboard prop. It can only support 5 pounds, but still looks pretty spectacular....

Here's a challenge for you: stuff over a dozen red lasers and a rechargeable lithium ion battery inside a tennis ball. Oh, and also a microcontroller and infrared port to control patterns from afar. To make your own, the author has...

Capacitive touch allows electronics to sense when your finger is within a few millimeters of a surface to simulate a button "press" without the use of an actual mechanical button. You'll notice the feature on the new Xbox 360 Slim. Here's a...

Learn how to build a custom interactive dance floor measureing 13x8 feet and containing 160 RGB LED illuminated squares. The project features eight microcontrollers which manage the LEDs, eight weight sensors, and an FPGA. The pressboard base...
